Question

the venn diagram shows the number of people in a group of friends who have brown hair and green eyes. what is the probability of a friend having green eyes?

Explanation:

Step1: Calculate total number of friends

Add all the numbers in the Venn - diagram: \(3 + 1+2 + 5=11\)

Step2: Calculate number of friends with green eyes

The number of friends with green eyes is \(1 + 2=3\)

Step3: Calculate probability

Probability \(P=\frac{\text{Number of friends with green eyes}}{\text{Total number of friends}}\), so \(P = \frac{3}{11}\)

Answer:

\(\frac{3}{11}\)
